Yes, it's really nice. The sections are fluentely sewed. And there is contrast and variation (in the variation itself).
Number VI was a bit strange because of the harmonic language, so modern, and bitonal (I think), or very chromatic. It's like an island in the other part of the piece, which is so romantic and tonal. I love this part, it's only the big contrast.
It's great music, and inspiring. I have many doubts about what I'm doing because it's also for piano solo (so different from an orchestral work) and because working with atonality it's being challenging.
Anyway, I enjoyed your work a lot.
Greetings!
